There is a way back from AVG 8...

in case of problems. I had problems in this process and this is the thread with my "experience".

Yet, the thing does not fit in my mind as to why eg Maple 11.02 Classic GUI was not affected. So, I have not reported to support as I was trying to guess a clue in some peculiarity of my system. But probably, because of scarcity of time for that, I will give up and report to support.

For those bad days...

of the system or not to lose time I find more practical to turn to the 2D ascii output  with 'interface(prettyprint=1)' .

I wonder whether algorithmic parameter splitting for integration is within the state-of-the-art. It sounds to me that it is not, and cases like this one, corresponding to singular limits of the general expression should be handled separately.

Following that link I have arrived at the site of LatexRender, which states:

Scripts that will render LATEX fragments into images for use with PHP programs such as phpBB forum , vBulletin forum, Simple Machines SMF, Claroline Course Management System, b2 blog, b2evolution, WordPress blog, simplePHPblog, Moodle, eZ publish, Drupal, Adaptive Website Framework or Wikis can be downloaded here (111KB)

I wonder why not using that script for Drupal here?

Polar axes?...

I wonder whether English speaking mathematicians do use the expression "polar axes" to denote coordinate lines in a curved coordinate system like the polar coordinates.

Not being an English speaker, the use of "axes" for "curves" sounds to me as an oxymoron, because an axis normally meant something rectilinear. Even more together with "polar" that means itself a direction.

Indeed, some googling has shown me that this strange usage is somewhat commonplace within the computing community. But I doubt whether this is a reason to endorse this usage.

Classic crashes...

The crashes of the Classic GUI are, in general, within the category of "non reproducible", ie unsuitable to make a standard SCR. Nevertheless, Microsoft presumably receives the reports of these crashes, as generated by Win XP.  I wonder  whether  Microsoft  has  any communication  with  Maplesoft  when receiving these reports. 

I have a frequency of crashes of Classic under Win XP of one or few per week. Many orders of magnitude higher than the OS. Ten years ago or so, with Maple V R5 say, under Win 95 (or 3.1) the situation was exactly the reverse.

 

embed css...

Presumably, using:

<style type="text/css">

css statements

</style>

within the head (<HEAD> </HEAD>), should work.

And the math problems...

The mecanism to generate gif files for 2d math through the <maple> tag is still  unstable (hence not reliable for serious documentation purposes in my opinion): One day I post and get it display right (with some fine tuning of the input), another day this mechanism does not work, showing broken code or a piece of the formula. Yet another day it works again...

I find that the mechanism latex-like code -> png used elsewhere works better.

the assumptions...

are used. Without them you get the same:

with(IntegrationTools):
simplify(len);
Change(%, x=xi^3,xi);                 
value(%);                    

                               1/2
                           20 10
                           -------- - 2/27
                              27

The "crItical point" is the change of variable. Is there an algorithm for finding the "natural" substitution?

3F2 not yet...

By the way, it seems that the hypergeometric 3F2 function is not much implemented in Maple for information and conversion yet.  Eg

FunctionAdvisor( hypergeom([a,b,c],[d,e],z) ,"identities");
...
Identities for hypergeom([a, b, c],[d, e],z) are unknown to 
the system


FunctionAdvisor( `3F2` );
No information is available on the topic: `3F2`. To see the 
topics for which information is available input:

and no 'convert/3F2'.

I find too this graphical environment so unrelated and unsuitable with the pretended subject of the wiki that I wonder how such a thing could come about. It could be that  the intention was honest (eg there is already a math wiki), but I could guess also that there is here a marketing technique: open fake wikis to catch hits for their ads.

at wikia......

By chance, I have met The Maple Wiki at wikia, which seems to be "empty"...
